Anybody have a pre-built script to concatenate .REG files?

As an adjunct to my script which runs WiseComCapture against a folder, it struck me that it would be useful to be able to merge the resulting .REG files into Wise Package Studio. Of course, importing a few .REGs is simple (apart from WPS's double-annoying propensity to switch its default folder back to 'Projects'...) but once you get beyond, say, 10, it starts to get very tedious. Thus, I had the idea to concatenate all the .REGs into one and import that. I could do it myself but if someone's done it already, that'll save me the job.
